IMPROVEMENT IN ELECTRO-MAGNETIC WATCHMENS TIME-RECORDERS.

Specification forming part of Letters Patent No. 198,814, dated January1, 1878; application filed September 12, 1876.

To all whom it may concern:

Be it known that I, WILLIAM E.-PnJsLPs, of Elmwood, in the county ofPeoria and State of Illinois, have invented certain new and usefulImprovements in Watchmens Electro- Magnetic Time-Reporters; and I dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich they appertain to make and use the same, reference being had tothe accompanying drawings, and to letters of reference marked thereon,which form a part of this specification.

This invention relates to electro-magnetic time-checks; and consists inthe construction, arrangement, and combination of the parts thereof, ashereinafter fully set forth 'and claimed.

The accompanying drawing is a perspective view of devices embodying myinvention.

Referring to the parts by letters, letter A represents a standard,carrying on its upper end an ordinary time-piece, B, the removable dial0 of which is graduated and numbered, in the usual manner, from I toXII, and is mounted on. the shaft 0, so as to rotate with it once intwelve hours. The dial 0 is also laid off in concentric circles DD.

Letters E E represent electro-magnets, the

one, E, connected by wires 0 c with a battery,

F, and circuit-closing key G, in the usual manner, and the other, E,connected with a battery, H, and circuit-closing key I by wires 0, alsoin the usual manner.

JJ are levers pivoted mid-length to standards K. The lower end of thelever J is attached to the armature L of the magnet E, and the lower endof the lever J is attached to the armature L of the magnet E. The upperend of each lever J J carries a prickpoint, m m, respectively, whichstand in close proximity to the face of the dial 0 when the levers arein their normal positions and the electrical circuits are open. Thepoints on m are arranged in line between a pointer, M, and the shaft 0.

The time-works B and electro-magnets E E may be fixed in an offiee,dwelling-house, or other desired place, (represented by letter N.) Thebatteries F H may be located as desired. The circuit-closing keys G andI are located in different parts of the works, or other place beingwatched, at stations where desired, and there may be any number of themrequiredone at each station-and each one connected, as shown in thedrawings, with a separate lever, J or J and the prick-points on thedifferent levers arranged to strike diii'erent ones of the concentriccircles D.

The dials O are printed on paper cards, and may be removed and renewedat pleasure. In placing them on the time-piece they should be placedwitht-heir figures and graduations representing the time of day at thepointer M. It will then be evident that if either key, G or I, is closedat a certain time or fixed mo ment, the attract-ion of the connectedarmature will operate the lever J or J, to which it is attached, andthrust the prick-point thereon into the dial 0, the mark leftrepresenting the time by its radial position on the dial, and theparticular circle D on which it is found representing the station wherethe circuit was closed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination, with a suitable recordingsurface, ofkeys G I, circuit-wires e 0, batteries F H, electro-magnets E E,armatures L L, upright elbow-levers J J, pivot arms or blocks K K, andmarkers m m, each circuit with its attached devices being independent ofthe other, so that an injury to one battery can affect the operation ofone pointer only.

In testimony that I claim the foregoing as my own I aifix my signaturein presence of two witnesses.
